Application April 30, 1956, Serial No. 581,726

1 Claim. (Cl. 128-75) This invention relates to and in general has for its object the provision of a traction or casting frame attachment for orthopedic tables.

Although orthopedic tables for performing various traction operations have long been on the market, they lack the necessary versatility or flexibility to conveniently make all of the adjustments required in various casting operations.

More specifically, the object of this invention is the provision of an open, generally rectangular frame of knock-down, tubular construction for the selective mounting on either both ends or sides thereof at any point thereon of one or more winches and provided with means for detachably mounting said frame to and above an orthopedic table.

The invention possesses other advantageous features, some of which, with the foregoing, will be set forth at length in the following description where that form of the invention which has been selected for illustration in the drawings accompanying and forming a part of the pres- In said drawings, one form of the invention is shown, but it is to be understood that it is not limited to such form, since the invention as set forth in the claim may be embodied in other forms.

Referring to the drawings:

Fig. 1 is a perspective view of an attachment embodying the objects of my invention with the orthopedic table to which it is detachably mounted shown in phantom.

Fig. 2 is an enlarged side elevation of the casting frame attachment illustrated in Fig. 1.

Fig. 3 is a vertical section taken on the section line 3-3 of Fig. 2.

Fig. 4 is a horizontal section taken on the section line 4--4 of Fig. 3.

As more particularly shown in Fig. l, the objects of my invention have been embodied in a generally rectangular frame 1 including parallel, tubular side beams 2 and 3 detachably secured at their ends to parallel, tubular cross members 4 and 5.

As best shown in Fig. 2, each end of each of the beams is provided with an outwardly extending threaded pin or stud 6 rigidly fastened thereto and arranged to pass snugly through diametrically aligned holes 7 formed in the ends of the cross members 4 and 5. Threaded over the free end of each of the studs 6 is a wing nut 8 serving to make a tight, rigid connection at each of the four corners of the frame 1.

Similarly connected to each of the tubular side beams 2 and 3, adjacent each end thereof, is a depending tubular post 9, and detachably connected to and between the lower ends of each transversely opposed pair of posts 9 is a crossbar 11. Extending through each crossbar 11, centrally thereof, is a pin 12 threaded at its upper end and arranged to extend between the parallel, transversely spaced rails or ways 13 and 14 of an orthopedic table generally designated by the letter T and shown in phantom in Fig. l. Secured to the lower end of each of the pins 12 is a U-shaped clamping member 15 arranged to straddle the ways 13, and threaded to the upper end of each of the pins 12 is a hand nut 16.

As a result of this construction, the frame 1 can be quickly attached to or detached from the orthopedic table T, and the entire frame, including its supporting legs 9 and crossbar 11, can be readily knocked and formed into a compact bundle for storage or shipping purposes.

Readily attachable to both the tubular side beams 2 and 3 and to the end cross members 4 and 5 at any selected point or points thereon are winches generally designated by the reference letter W. As clearly illustrated in Figs. 2, 3, and 4, each of the winches includes a post 17 provided at its lower end with a collar 18. Partially sur rounding each collar 18, and secured thereto and to its associated post 17 by a threaded pin 19, is a clamp channel 20 extending substantially below the lower end of the post and its collar. Formed adjacent the lower end of each of the clamp channels 20 on each edge thereof are opposed semicircular notches 21 of a diameter sufliciently large to receive or straddle the beams and cross members 4 and 5 of the frame 1. Pivoted to the bifurcated, enlarged end or head 22 of each pin 19 is an L-shaped clamping rod 23 threaded at its outer end and provided adjacent its bend with one or more teeth 24. As best shown in Fig. 3, the clamping rod 23 is receivable in a vertical, central notch 24a formed in the lower central portion of the channel 20 so as to form therewith a clamp closing over one of the members 2, 3, 4, or 5. Threaded over the free end of the clamp rod 23 is a cylindrical nut 25, and attached thereto, transversely thereof, is an operating rod or handle 26.

Journaled and slidable on the upper end of the post 17 is a pair of collars 27 and 28, and secured thereto and therebetween is a pair of diametrically opposed rods 29 and 31 in parallelism with the post 17 and radially spaced therefrom. Attached to the upper collar 27 is a radially extending rod or crank 32, and threaded through the opposite side of said collar is set screw 33 terminating in an operating handle 34.

As a result of the clamp provided on the lower end of the winch post 17, one or more winches W can be clamped to any one or more of the frame sides or ends 2, 3, 4, and 5, as illustrated in Fig. 1, either in a vertical position or in any desired inclined position.

Securable to each of the winches W through and to one of the winch rods 29 and 31 are the free ends of a traction cord 35, the intermediate looped end thereof being threaded through one of the rings 36 of a head halter 37, pelvic belt 38, and/or canvas yokes, etc. By rotating the winches through the cranks 32, any desired tension can be placed on the cord 35, and then each winch c can be locked against rotation by tightening up on its set screw 45.

Slidable on the frame sides 2 and 3 are clamps 41, and adjustably mounted therein are posts 42. Pivoted to the upper ends of two of such opposed posts 42 is a plate 43 arranged, for example, to support the legs 44 of a patient P in conformity with the inclination thereof.

As a result of my casting frame attachment, maximum results can be obtained in applying anti-gravity, tumbuckle, localizer casts, etc. to the body in various corrective positions.

I claim:

An attachment for orthopedic tables comprising: an open, tubular, generally rectangular, horizontally disposed frame including opposed sides and opposed ends; a leg secured to and depending from said frame adjacent each corner thereof; a crossbeam secured to and between the Patented. July 7, 1959,
